The QNAP TVS-673 lets you build a tailored NAS storage system for connected users by featuring four Gigabit Ethernet ports as well as six 2.5"/3.5" storage bays and two M.2 slots. This design offers multi-tiered storage options, allowing the TVS-673 to utilize ultra-fast SSDs and high-capacity hard drives side-by-side. You can use optional M.2 SSDs as cache memory, which enhances the delivery of data stored on the hard drives. To manage your data and a QTS 4.3 operating system. it sports a 2.1 GHz AMD RX-421BD quad-core processor along with 64GB of DDR4 memory. The AMD APU has speeds of up to 3.4 GHz and comes with an embedded Radeon R7 graphics processor, which delivers up to 3840 x 2160 visuals through two HDMI ports. There's also a built-in hardware transcoding engine that provides optimal video resolutions for your various devices.

Other notable connections include three audio jacks, four USB 3.0 ports, and two USB 3.1 ports with 10 Gb/s speeds. The four Gigabit Ethernet ports offer teaming and failover support so the TVS-673 can quickly provide always available data. For supporting a greater number of users, you may install a sold-separately 10GbE adapter in the TVS-673's PCIe 3.0 x4 slot.

Once drives are installed into the NAS server, you can configure your drives in a RAID 0, 1, 5, 6, 10, 5 + hot spare, or JBOD mode. To safeguard data, AES-NI encryption is on board. Moreover, the QNAP TVS-673 can perform real time or scheduled data backups to a remote NAS or FTP server as well as a rsync function that backs up data stored on this server to another remote server on a scheduled basis, such as cloud storage.

Performance and Security

The TVS-673 is equipped with an AMD R-Series RX-421BD quad-core 2.1 GHz APU (burst up to 3.4 GHz), dual-channel 64GB DDR4 RAM, and four Gigabit LAN ports. It can deliver up to 1,172 MB/s throughout with an optional 10GbE adapter.
